The differential is a device that allows the wheels on an axle to rotate at different speeds while still receiving power from the engine.

• Allows wheels on the same axle to rotate at different speeds

• Transfers power from the engine to the wheels

• Helps with cornering by allowing the outer wheel to rotate faster than the inner wheel

• Consists of gears that distribute power evenly to the wheels

The dumper cooling system is responsible for maintaining the optimal temperature of the dumper to prevent overheating.

• Regularly check the coolant levels and top up if necessary.

• Inspect the radiator for any leaks or damage.

• Clean the radiator fins to ensure proper airflow.

• Monitor the temperature gauge regularly while operating the dumper.

• If the dumper overheats, stop immediately and allow it to cool down before continuin

Work permit system is a formal process to ensure safety during maintenance activities.

• Obtain necessary permits before starting any maintenance work.

• Identify potential hazards and implement necessary safety measures.

• Communicate with all involved parties about the work being done and safety precautions.

• Regularly review and update work permits as needed.

• Examples: hot work permit, confined space entry permit, electrical wo

The grade of oil used in a hydraulic system depends on the system's requirements and manufacturer recommendations.

• The grade of oil used in a hydraulic system is typically specified by the system manufacturer.

• Common grades of hydraulic oil include ISO VG 32, ISO VG 46, and ISO VG 68.

• The grade of oil chosen should meet the viscosity and performance requirements of the hydraulic system.
